From Seoul Through Pictures 5: Expanding Seoul (1971-1980) (published by The City History Compilation Committee of Seoul) comes this 1976 poster calling for preparation for emergencies showing life necessities needed for an emergency kit for a family of five intended to last 10 days. On the bottom it says 'Let's all prepare emergency supplies!'
The emergency necessities include, clockwise from top, 30kg of mixed grains (an average of 600g per person per day), 30 yontan, one 500g bag of sugar, one 600g bag of salt, a flashlight, 12 candles, and one 350g bar of soap.
Somehow I imagine the needs of a family today would be quite a bit more.
